Top 10 Plumbing Issues in Multi-Unit Properties and How to Fix Them

Plumbing Issues

Property managers across Canada face unique challenges when it comes to maintaining plumbing systems in multi-unit commercial properties. From Vancouver's coastal humidity to Toronto's freezing winters and Montreal's temperature extremes, common commercial plumbing issues can disrupt operations, increase costs, and frustrate tenants.  

Facility Network specialises in providing comprehensive plumbing services and maintenance solutions designed specifically for Canadian property managers overseeing retail spaces, office buildings, and commercial complexes. 

This guide explores the ten most frequent plumbing challenges in multi-unit properties and provides actionable pipe blockage solutions, water heater problems remedies, and drain cleaning best practices to help you maintain operational excellence. 

1. Frozen and Burst Pipes 

Extreme seasonal temperature shifts represent a primary environmental factor for Canadian plumbing infrastructure. In many regions, temperatures regularly drop low enough to cause water inside pipes to freeze and expand, leading to ruptures. 

Solution: Implement preventive insulation on exposed pipes, maintain consistent indoor temperatures, and install heat tape in vulnerable areas. For multi-site properties, coordinate regular winterisation inspections across all locations before cold weather arrives. 

2. Chronic Pipe Blockages 

Pipe blockage solutions are among the most requested services for multi-unit properties. Blockages caused by grease buildup, foreign objects, and mineral deposits are a frequent issue in commercial buildings. 

Solution: Establish quarterly professional drain inspections, install grease traps in food service areas, and educate tenants about proper disposal practices. Hydro-jetting can provide effective clearing for stubborn blockages when performed by qualified professionals.

 

3. Water Heater Failures 

Water heater problems can disrupt daily operations and impact tenant satisfaction. Commercial water heaters require regular upkeep to operate reliably and avoid unexpected breakdowns. 

Solution: Schedule routine water heater inspections, perform periodic tank flushing to reduce sediment buildup, and replace worn internal components as needed. Consider upgrading to tankless systems to improve energy efficiency and reduce space requirements. 

4. Leaking Faucets and Fixtures 

Commercial fixture leaks, including those in high-traffic restrooms and kitchens, account for significant water waste. Even intermittent drips can waste more than 35,000 litres of water annually, increasing utility costs and stressing municipal water resources. Left unaddressed, dripping faucets and minor plumbing issues can significantly increase utility costs. 

Solution: Implement a centralised maintenance tracking system to log and address all reported leaks within 24 hours. Replace worn washers, O-rings, and cartridges promptly. For properties across multiple sites, Facility Network's vendor coordination services support consistent response times. 

5. Sewer Line Backups 

Sewer line issues represent serious health hazards and costly repairs. Tree root infiltration, aging infrastructure, and improper waste disposal contribute to backups. 

Solution: Conduct annual video camera inspections of main sewer lines, establish root barrier treatments, and maintain detailed documentation of sewer line conditions. Municipal Sewer Use Bylaws require proper waste management protocols, support compliance across all locations. 

6. Low Water Pressure 

Low water pressure affects tenant comfort and equipment functionality. Causes include mineral buildup, corroded pipes, and municipal supply issues. 

Solution: Install pressure gauges to monitor system performance, clean or replace aerators regularly, and assess whether pressure-reducing valves require adjustment. For buildings with aging infrastructure, consider copper or PEX pipe replacement projects. 

7. Running Toilets 

Even small leaks can result in substantial water waste over time. Left unaddressed, dripping faucets and minor plumbing issues can waste hundreds of litres per day and significantly increase utility costs. 

 

Solution: Implement drain cleaning best practices that include regular inspection of flapper valves, fill valves, and flush mechanisms. Upgrade to high-efficiency toilets that meet specifications for water conservation. 

8. Corroded Pipes 

Canada’s varied water chemistry can accelerate pipe corrosion, particularly in older buildings. Over time, materials such as galvanized steel and copper naturally deteriorate, increasing the risk of leaks, reduced water quality, and system failure. 

Solution: Conduct comprehensive plumbing assessments during property acquisitions, prioritize pipe replacement in renovation budgets, and consider modern materials like PEX or CPVC for superior longevity and freeze resistance. 

9. Faulty Pressure Regulators 

Pressure regulators protect plumbing systems from municipal supply fluctuations. When these fail, excessive pressure can damage fixtures, appliances, and pipes. 

Solution: Maintain pressure within ranges recommended by the manufacturer and local building codes to protect system integrity. For multi-unit properties, coordinated testing across locations prevents system-wide issues. 

10. Drainage System Failures 

Poor drainage creates flooding, structural damage, and mould growth. Canadian building codes mandate specific drainage requirements, but aging systems often fall short. 

Solution: Implement comprehensive drain cleaning best practices including monthly maintenance schedules, enzyme treatments for organic buildup, and professional hydro-jetting for main lines.

  

Seasonal Plumbing Maintenance Checklist for Canadian Properties 

Season Maintenance Tasks Priority Level
Fall Pipe insulation, outdoor tap winterisation, boiler inspection Typically addressed as a high priority before the first freeze.
Winter Monitor for frozen pipes, check heating systems, emergency preparedness Generally considered critical for maintaining operational continuity.
Spring Inspect for winter damage, test outdoor systems, drain clearing Often prioritized to address potential freeze-thaw damage.
Summer Water heater maintenance, pressure testing, fixture upgrades Typically scheduled as routine preventive maintenance.

Multi-Site Maintenance Challenges in Canada 

Managing plumbing across multiple properties requires sophisticated coordination. Geography spans six time zones, weather varies dramatically between regions, and provincial regulations differ significantly. Successful property managers leverage centralised vendor management systems and establish relationships with qualified regional plumbing contractors.

Frequently Asked Questions 

1: How often should commercial drains be professionally cleaned?  

Commercial drains should be professionally cleaned quarterly to prevent blockages. High-traffic properties like restaurants may require monthly service, while office buildings can extend to semi-annual cleaning depending on usage patterns and drain performance. 

2: What causes frozen pipes in multi-unit buildings?  

Frozen pipes result from inadequate insulation, exterior wall exposure, and insufficient heating in vacant units. Temperatures sustained sub-zero temperatures combined with poor air circulation create freezing conditions. Preventive insulation and temperature monitoring prevent this costly problem. 

3: How can property managers reduce water heater repair costs?  

Regular maintenance, including annual inspections, periodic tank flushing, and timely anode rod replacement, helps extend water heater lifespan and reduce the likelihood of unexpected failures. Proactive maintenance is often viewed as a strategic approach to managing long-term operational costs.  

4: What are the best practices for preventing sewer backups? 

 Annual video inspections, root barrier treatments, proper waste disposal education, and backwater valve installation prevent most sewer backups. Documentation of sewer line conditions helps predict problems before they occur, reducing emergency response needs. 

5: How does climate affect plumbing maintenance in Canadian properties?  

Canada's temperature extremes require seasonal adjustments including winterisation, spring thaw inspections, and summer efficiency checks. Regional differences mean coastal properties focus on corrosion while prairie properties emphasize freeze protection and hard water management. 

6: What should property managers look for when hiring plumbing contractors?  

Verify provincial licensing, liability insurance, emergency response capabilities, and multi-site service experience. Contractors should understand local building codes, offer preventive maintenance programs, and provide detailed documentation for all work performed across property portfolios.
